Taoiseach Bertie Ahern is to meet British Prime Minister Tony Blair on Friday morning to discuss the early results of the Northern Ireland Assembly elections.
The leaders, who have worked side by side on the peace process for a decade, will hold talks on the fringes of the European Council's spring summit in Brussels.
Voters go to the polls tomorrow and early indications of the state of the parties should be known by the time Mr Ahern and Mr Blair meet.
Almost 250 candidates in 18 constituencies will be vying for 108 seats in the Assembly.
The Democratic Unionist Party (DUP) and Sinn Fein are expected to be the largest parties and will be urged by the two governments to share power in devolved institutions.
As the pace of developments increases, Minister for Foreign Affairs Dermot Ahern will hold talks with Northern Secretary Peter Hain next Monday.
The Independent Monitoring Commission (IMC), which acts as a watchdog for paramilitary ceasefires, is also due to issue its latest report next week.
Government officials in Dublin will keep in close contact with their US counterparts in Washington in coming days.
The Taoiseach today briefed the Cabinet on the latest developments in relation to Northern Ireland at its weekly meeting.
"Mr Ahern said the two governments and the political parties were entering into an intense period of activity in the following three weeks," his spokeswoman said.
According to the timetable set out under the St Andrew's Agreement, the power-sharing institutions must meet on March 26th.
